Which situation represents a proportional ralationship

A situation represents a proportional relationship if you can write equivalent ratios of related quantities in that situation.

Step-by-step explanation:

The proportional relationships can be represented in many ways:

i)One way is considering a straight line graph passing through the origin.

ii)A verbal description describing the directly proportional relationship between two quantities.

iii)An equation y=kx, here k= constant of proportionality.

For example:

1/2 and 5/10 have a proportional relationship

Both of them are same.

The proportional relationship can help in dealing with the real life problems. Some of them are scaling a diagram, adjusting a recipe and finding increase/decrease in percentage.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
